TYPEVRITING MACHINE.

Application filed June 16, 1919. Serial No. 894,532.

To all whom it may concern.

Be it known that I, Jnssn A. B. SMITH, a citizen of the United States,residing in Stamford, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inTypewriting Machines, of which the following is a specification.

This invention relates to typewrltlng ma- 1 chines, and is hereindisclosed as applied to.

an Underwood standard typewriting machine.

The invention is herein disclosed as embodied in a device adapted tofacilitate the simultaneous entering of single items upon a bill headand a ledger sheet, and more especially adapted for use in such workwhere a single item only is entered daily on each bill and the ledgersheet.

In order to facilitate making such entries, it is advantageous to havean end gage which is adapted to be positioned in'the machine,

so that a work-sheet, for example a bill, may

be gaged thereagainst, in a predetermined 2 position and so that anotherwork-sheet, for

example a ledger sheet, may be gaged against another end gage settablewith reference to the first gage, thus enabling the sheets to beinserted with a minimum of labor, conducing to accuracy and rapidity ofwork. T

In order to enable a typewriting machine used for this work to be alsoused for other purposes, it has been found advantageous to provide aspecial paper table at the rear of the 1 platen, forward from the usualpaper table in spaced relationthereto and adapted to carry the gage forthe work-sheet, and so positioned as to guide the work-sheet down Otherfeatures and advantages will here In the accompanying drawings,

Figure l is a perspective view of an Underwood standard platen frame orshift frame, showing my invent-ion as applied thereto.

Figure 2 is an enlarged section of the end gage, and the meanswhereby itis adjusted.

Figure 3 is a sectional side View of the parts shown in Figure 1, andshowing a ledger sheet positioned.

Figure 4 is a view similar to Figure 3, but showing the feed-rollseffective, and a bill gaged againstthem Figure 5 is a view similar toFigure 4:, but

showing the ledger sheet and. the bill advanced to the printing point.

A work-sheet 10, which may be a ledger sheet,,is passed around theplaten,11,'which is journaled in the ends 12 of the usual Underwoodshift frame, by being slipped down over a paper-guide which may be asecond paper table 13, mounted upon brackets 1 L springing from the ends.12 of the shift frame and lying between the platen 1'1 and the usualrear paper table 15. The paper table 18 may be considerably narrowerthan the platen 1 1 and rear paperjtable 15, and

advantageously extends down below the cross piece 16, which is fast toit andwhich supports it upon the brackets 14. The paper table 13. asclearly seen in Figures 3 and 4, terminates considerably short of theplaten l1, and above the point where the usual paper table 15terminates, thus leaving a clear space between the two tables for theinsertion of ordinary work-sheets.

When the. work-sheet 10 is slipped down upon the paper table 13, itstrikes the lower end 17 ofthe paper table 15, and is bent forwardly topass between the usual rear feed roll 18 and the platen 11. and fromthence swings forwardly above the front feed roll- 19, up past theprinting point'indicatedin Figure 5 to the point at which the lowercasetypes 20strike against the work-sheet. Wheninserted in this manner, thetrailing edge of the work-sheet 10 may begaged against atransverse barmember forming an end gage 21. whlch is formed as an L on a plate 22,said plate being adjustably fast c ded o h en y means of th m -nuts 23,which are adapted to be screwed up upon screws 25 extending throughopenings 241 in the table 13, to draw down the plate 22 upon the face ofthe table. When thus adjusted, the work-sheet 10 is gaged at itstrailing edge by moving the work-sheet upwardly against the L end gage21, gaging it beneath a pair of lightly pressing spring clips 26, whichbear upon the front of the table 13 or upon a front extension 27 of theplate 22.

The work-sheet 10 may be further gaged at this time'by means of the sidegages 28,. which are shown as termed of turned-up ends of the extension27. In order to facilitate the rapid centering of the work-sheet 10, thelower ends 29 of the side gages 28 may flare outwardly, and to enablethe work sheet 10 to be easily handled, the side gages 28 may be onlyjust long enough to give a good bearing for the edge of the work-sheet.

The feed-rolls 18 and 19 may now be drawn against the platen byoperating the usual casting-off handle 32. When a worksheet has beenthus adjusted and is held in place by the clips 26 and feed-rolls 18 and19, a second work-sheet 30, in the form ota bill head, together with acarbon 31, maybe inserted, usually between the worksheet 10 and theplaten 11. as shown in Figure 4, although obviously if desired theworksheet 30 and carbon 31 may be insorted, in proper relation, at theback of the second paper table 13 and on theusual paper: table 15, whichforms a part of the usual platen vframe having the ends 12. Thework-sheet 30 may be'passed downwardly until it seats itself against thebite of therearieedrolls 18, which, in this way, form a leading edgegage for the sec ond -work-sheet. When the work-sheets have been thusbrought to the proper position relatively to each other by rolls or'gages'18 and the gage 21, the platen may be rotated-forwardly either byactuating the usual line-spacemechanism. which includes the linespacewheel or by rotating the knob 34 until the line to receive thetypewritten matter is at the printing point where the types 20 can writeupon it. It is to be noted that the rear feed-rolls 18 may serve as aleading-edge gage for a worksheet inserted t'rom the rear the front ofeither of the paper tables 13 to 15.

Owing to the fact-that the clips 26 hold the first work-sheet lightly,the two work- "sl'ieets'advance together to 'the printing pointatthe-turning of the platen. After v the desired line of writing has beenwritten.

the work-sheetsare-removed from the ma- $111118, "and another first andsecond worksheet-10 and 30 are inserted in the same manner.

-It wi-lhbeobserved that the device is of especial'utility whereentriesare to be made at a. distance from the of: a arge numgage 21 may beadjusted to suit this distance, viz, the distance from the end gage 21to the writing line upon the bill 30, when the latter is gaged againstthe feed-rolls 18.

To facilitate the rapid and accurate adjustment of the end gage 21, asuitably graduated scale may be provided at each end of the table 13,the graduations being co-ordinated with the position of the line toreceive the printing upon the bill head 30 when the latter is gagedagainst the feedrolls 18.

Variations may be resorted within the scope of the invention, andportions of the improvements may be used without others.
